The first strap 31 is located between the headrest 2 and the second strap 32, and the second strap 32 is located between the seat body 1 and the first strap 31. Compared to the traditional method of using complex pins and locks to connect the headrest and seat body, the headrest 2 and seat body 1 in this embodiment are connected by a strap mechanism, resulting in a simple structure and low production cost.
[0028] The first strap 31 can be connected to the seat body 1 in several ways. It can be fixed by sewing both ends of the first strap 31 to the seat body 1 with needle and thread; alternatively, two first through holes can be made on the seat body 1, and the two ends of the first strap 31 can be passed through each hole and then secured by binding; or two first through holes can be made on the seat body 1, and buckles can be set at both ends of the first strap 31, allowing for a detachable connection by passing both ends of the first strap 31 through each hole. This connection structure is simple and low-cost.
[0029] Similarly, the second strap 32 and the headrest 2 can be connected in several ways. For example, the two ends of the second strap 32 can be sewn onto the headrest 2 for a fixed connection; alternatively, two second through holes can be made on the headrest 2, and the two ends of the second strap 32 can be passed through these holes one by one, then secured by binding; or two second through holes can be made on the headrest 2, and buckles can be set at both ends of the second strap 32, allowing for a detachable connection by passing the two ends of the second strap 32 through the holes one by one. This connection structure is simple and low-cost.
[0030] Since the headrest 2 is movably mounted on the seat body 1, it can be moved up or down along the inner wall of the seat body 1 during use to adjust the relative height between the headrest 2 and the seat body 1, providing appropriate head support for children of different ages.
[0031] like Figure 2 and Figure 3As shown, in some embodiments, the first strap 31 and the second strap 32 are configured according to Embodiment 1, that is, the two ends of the first strap 31 are connected to the seat body 1 and the length direction of the first strap 31 is parallel to the moving direction of the headrest 2, and the two ends of the second strap 32 are connected to the headrest 2 and the length direction of the second strap 32 is perpendicular to the moving direction of the headrest 2. Since the first strap 31 is parallel to the moving direction of the headrest 2, the first strap 31 has a guiding function. When the headrest 2 is moved relative to the seat body 1, the second strap 32 connected to the headrest 2 moves along the length direction of the first strap 31 connected to the seat body 1. The structure is simple and the movement is convenient.
[0032] like Figure 4 and Figure 5 As shown, in some embodiments, the first strap 31 and the second strap 32 are configured according to Embodiment 2, that is, the two ends of the first strap 31 are connected to the seat body 1 and the length direction of the first strap 31 is perpendicular to the moving direction of the headrest 2, and the two ends of the second strap 32 are connected to the headrest 2 and the length direction of the second strap 32 is parallel to the moving direction of the headrest 2. Since the second strap 32 is parallel to the moving direction of the headrest 2, the second strap 32 has a guiding function. When the headrest 2 is moved relative to the seat body 1, the first strap 31 connected to the seat body 1 moves along the length direction of the second strap 32 connected to the headrest 2. The structure is simple and the movement is convenient.
[0033] Furthermore, the child car seat headrest connection structure of this embodiment also includes a child safety belt 4 disposed on the seat body 1. The child safety belt 4 includes a shoulder safety belt 41, and the headrest 2 includes a headrest module 21 and a backrest module 22. The backrest module 22 is provided with a backrest through hole 221 for the shoulder safety belt 41 to pass through.

[0034] Furthermore, the headrest module 21 has headrest protrusions 211 at both ends. The headrest protrusions 211 at both ends of the headrest module 21 can effectively limit the child's head, better fix the child's head, and provide protection for the child's head.
[0035] Furthermore, the seat body 1 is provided with a limiting slide groove 11, and the headrest 2 is movably disposed on the limiting slide groove 11. The limiting slide groove 11 is provided with baffles on the left, right and lower sides of the headrest 2. The limiting slide groove 11 provides a limiting function for the headrest 2 on the one hand, and a guiding function for the headrest 2 on the other hand, so that the headrest 2 moves more stably and smoothly.
[0036] Specifically, the child safety belt 4 also includes a crotch strap 42, a locking buckle 43, and a tensioning mechanism 44. The tensioning mechanism 44 is mounted on the seat body 1. One end of the shoulder strap 41 is connected to the tensioning mechanism 44, and the other end is connected to the locking buckle 43. One end of the crotch strap 42 is connected to the seat body 1, and the other end is connected to the locking buckle 43. The tensioning mechanism 44 is used to tighten or loosen the shoulder strap 41. When the tensioning mechanism 44 tightens the shoulder strap 41, the length of the end of the shoulder strap 41 that engages with the child's shoulder is fixed. When the tensioning mechanism 44 loosens the shoulder strap 41, the length of the end of the shoulder strap 41 that engages with the child's shoulder is fixed and adjustable, making it suitable for children of different ages.
[0037] Furthermore, the tensioning mechanism 44 includes a tensioning block hinged to the seat body 1. The tensioning block has a pressing part 441 and a releasing part 442. The thickness of the pressing part 441 is greater than the thickness of the releasing part 442. When the tensioning block rotates to the point where the pressing part 441 contacts the shoulder seat belt 41, it presses the shoulder seat belt 41. When the tensioning block rotates to the point where the releasing part 442 is opposite to the shoulder seat belt 41, it releases the shoulder seat belt 41. When the tensioning block rotates to the point where the pressing part 441 contacts the shoulder seat belt 41, it presses the shoulder seat belt 41, at which time the length of the end of the shoulder seat belt 41 that engages with the child's shoulder is fixed. When the tensioning block rotates to the point where the releasing part 442 is opposite to the shoulder seat belt 41, it releases the shoulder seat belt 41, at which time the length of the end of the shoulder seat belt 41 that engages with the child's shoulder is fixed but adjustable. A return spring or torsion spring is also provided between the tension block and the seat body 1 so that the tension block keeps its pressing part 441 in contact with the shoulder seat belt 41 to press the shoulder seat belt 41 before being subjected to external force.
[0038] Furthermore, the clamping part 441 is provided with clamping teeth, which makes the clamping part 441 and the shoulder safety belt 41 more stable.
[0039] Additionally, the tensioning mechanism 44 may include a torsion spring or other elastic return element to keep the tensioning block pressed against the shoulder seat belt 41 when not subjected to other external forces. The locking buckle 43 in this embodiment uses a buckle commonly found in commercially available child car seats.
[0040] Furthermore, the headrest 2 is connected to the seat body 1 via Velcro. After the headrest 2 is moved relative to the seat body 1, the headrest 2 is connected to the seat body 1 via Velcro, which can maintain the relative position of the headrest 2 and the seat body 1.
